There are actually 6 events that were created in the previous revision (each center ring girl plays a prank on the other two). They are triggered by having one of the girls love points low. They play pranks on the girl that is favoured. Just another reason, why using a mod to distort game variables is counter-productive.
I don't use any mods. I assume you mention this because of what is available and how easy it is to break the game/code for event triggers. I think my problem is more in the repetitive nature to access/trigger these events since I just continued my game instead of starting anew. It might be easier to trigger more of these scenes from a fresh start or at the least be less repetitive since you to have neglect some girls and spend time/sleep more with others? considering I have more than enough in game credits and could purchase all the ship upgrades and the "get-away" retreat without too much hassle there isn't much incentive for me to play around so much to trigger "events/scenes" of this nature especially since I wasn't aware of them and they don't show up in the quest tracker? I haven't seen it mentioned in the changelog either. However now that I am aware of them I am curious about them

Might even do a replay or might wait for next update for that..
This being said, it seems it is a little obtrusive in what content is available since I wasn't aware of it I didn't look for it and just stumbled upon that scene by chance. Again, this could be more of a me problem than anything game related though..
The game design suffers a little from the structure of 7 day x 5 time periods x 8 crew members (280 potential interactions). If you create content for each girl at each time period, it would be bigger than most games just by itself. Populating the ship to make it feel truly alive is unfortunately impractical from a work / time perspective.
Yes, unfortunately I find myself skipping time very often now just to get from point a to b.
The dialogue from the pirates is a little underwhelming at this stage. I will endeavour to tweak to give each of them a distinctive flavour.
It comes down a little to priority of the girls and the amount of content that can be created. This is in part why the content for characters such as Julia / Rachel / Alice is less than the remainder.
I'll give it some thought, however it comes down to work required. To display in the room I would need to create at least 13 new navigation screens. Then I would have to check other content to see whether it is visible in other shots within the game. My original game design seemed good at the time, however due to my inexperience back then, I have created some inflexibility in creating adjustments.
I will potentially add some more training (sword combat). However this is largely dependent upon whether I can find a good use for the trained skills such that putting in the effort will actually have an effect to the main story line.
I see, and that's understandable there are so many things right with this game which I haven't mentioned. Was just trying to get my player experience across and hopefully it gives some feedback or things to think about. For instance the gift you get from Kara would be a great setup for achievements(steam), trophy case what ever, besides its something that means/meant a lot to her so I feel like it would have been "fitting" and deserving. But this could just be my weakness for her or my idea of swords/katana's being bad ass

and the idea of training more with Kara seemed like a fantastic prospect as well. I have no idea where you are going with it story wise, but it's almost a shame that the MC doesn't have player stats that are being developed as you progress those events with her.
And it also seemed expandable with other things you might acquire from either crew or things you find on other planets/quests.
But like you said, I have no idea where you are taking the main story line, and if it would be fitting at all, aside from having to put the work in cause I imagine to create something like this also takes compromise and there is plenty of things I would like to see implemented further as well
